My Indoor Grow - Rust or deficiency? - All the info you need to help me is enclosed

Attachment 290878Attachment 290879Attachment 290880Attachment 290881

Think i have a rust problem or a deficiency ive filled out the form below:

There are no rusty spots on the back of the plant, this is only happening on the front.

Its on the lower leaves but also some of the higher leaves.

These plants are 10 weeks old and in VEG, they should be bigger but they were in a 3 gallon for 7 weeks.

My guess is ive been feeding too low and the plant is a bit weak, my run off PPM is 550-600 and thats with using 400ppm well water to do the test. so theres fuck all for nute in the soil.

This is happening to most of my plants, more so in the room with less humidity (30-40%) ive taken pics of the most infected plant

These plants are 3-4 feet tall and in a 10 gallon container with very good looking roots, how ever they need to be trans to a larger container as the branches are now wider than the pot.

Ive also taken a pic of the back of one of the infected leaves. First Picture

Ive also got some weird wrinkling/waffling going on with some of the green leaves, the last picture shows this.

Any help is appreciated, i feel like ive given the best possible info. If you need to know anything else please ask. Id prefer to deal with people who have experience and who can explain in an intelligent way about whats going on. Its my guess that i need to sauce em with a good load of nute and get the humidity up, as well as remove all infected leaves.

11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)
Tri meter digital PH, PPM and Temperature. Always calibrated

12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)
I use PH up, but very little

13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.
General Hydro 750ml green, 500ml brown, 250ml pink, into a 50 gallon reservoir. Feed, feed, Water. Usually soak the pots till it runs out the bottom then let them dry and feed again etc.

16) Are your ph levels stable, or do they fluctuate?
Fairly stable

17) What is your ingoing water's ph? ...your runoff ph?
Ingoing: 6.6 (when i feed or water) When i check run off i just use straight well water which is 7.1, its coming out at 7.0

I could guess but id probably be wrong. Im just basically replying to give you props for adding pics and a filled out troubleshooting form. Hopefully someone will pipe in and help you out. BTW, welcome back to the board!

Thanks bro, ive seen far too many posts saying shit like "ive got spots on my leaves, whats wrong???" and didnt wanna be one of those knobs. lol

10 weeks is a lil long for indoors but if height isnt problem its no worries. looks a bit like nute burn, try flushing them and cut your solution strength in half for a couple go rounds and see if that does it.

Thanks for the reply Mal, agreed 10 weeks is super long, just the way its working out though, got lots of space, and gunna trans em into 30 gal geo pots soon.

I cant see it being nute burn, the run off is 550, doesnt make sense. IF it is, they aint gunna like what i just gave em, lol.

Thanks

550 isnt much, any changes you might have made recently even ones that might seem small? or spray/drip/splash anything?

I had flushed, and then re fed, but its a new room and a new irrigation system, so i wasnt aware of how much fert to put in after flushing, i think i got it now though, i just sauced em with 1500ppm and the run off is between 1000 and 1400, so hopefully that perks em back up and rectifys the prob.

keep us updated then

A lot of variables. I'll say again as our prolific moderater states "it's a weed". Personally feel like you have so many things going on that me head was spinning reading them? You appear extremely intelligent so do the math. I'd say scale back on the nutes? They are usually the culprit but I'm green horn. Just an opinion!

Sic Semper Tyrannus

:wtf:

That's a lot of light. What's the power bill like?
Looks like too much fert has been given, dark green leaves and a feed, feed, water schedule is a lot of fert. I think you're pushing them to the edge.
You're humidity is fine. Transplant when you can and go easy on the ferts.
